Can digital waveform editor be launched from labview8.6

Hi,
Have anyone tried launching digital waveform editor from labview8.6? if so please let me know.Is there any connectivity VI that can be used for waveform editor.
Thanks,
Nandhini

Nandhini,
You have two different options for interacting between the Digital Waveform Editor and your hardware. You can either use the play button directly from the Digital Waveform Editor to launch Signal Express with a HSDIO Express Step configured to generate the waveform you are creating in the DWE, or you can edit and save a waveform to disk, and then configure a LabVIEW program to generate that saved waveform. It sounds like the second method is what you are looking for. Save the waveform you are editing in the DWE to disk at a specific location, then configure your LabVIEW VIs to generate the waveform, and use either the HWS read VIs, or you can use the write waveform VIs of the HSDIO and specify the location of the HWS file.

Digital waveform editor can not open hws file generated by niHWS store waveform

Hi,
I am using a simple VI to store the U32 array to a hws file in LabVIEW, however, the file generated can not be opened by Digital Waveform Editor. The VI used to be working well before I upgrade LabVIEW from V7 to V7.1.
Meanwhile I also found out that the hws file generated by DWE can not be read out by niHWS. retrieve waveform.vi if the number of channels is not 32.
I would be grateful if any one can give me some help. Please find the VIs and hws files as attached.
The software I am using is
Digital Waveform Editor 1.0
LabVIEW 7.1

question Get ArrayU32 from HWS Data.vi ‏108 KB

Dear Brian,
Thanks for your quick response.
I tried again but still failed to open the hws file with my DWE V1.0. Since the version is the only difference between our software, I suspect the problem is caused by my DWE of old version.
Would you please help me to check if the new attached questionretrievepattern.hws file can be opened by the HWS.VI? (Please change the extention from txt to hws as I can not attach file with hws format in this forum)This file is generated by DWE1.0 and contain only 16 channels. It can not be opened by the niHWS retrieve waveform.vi in my computer with erroe code "-21558", but if I added another 16 channels signals with DWE, the data can be read out properly.
If we can confirm the problem is caused by DWE1.0, would you please also let me know how to upgrade my DWE? Thanks.

Digital waveform editor sample size limit?

Hi,
Can anybody please tell me the sample size limit of the Digital Waveform Editor? Thanks!

Hello,
1) You can actually acquire as many points as you want. You may be worried about the throughput of all this data from the DAQ board into computer memory, but I don't think this will be much of a concern for your application. You're limited only by how much memory your computer has. Mainly, you should be concerned about what you are doing with all those samples after they are acquired. Are you just using them once then throwing them away? (Such as the "Cont Acq&Graph Voltage-Int Clk.vi" shipping example.) Or are you streaming them to disk? If you just keep them all in computer memory, then there would be some maximum number of samples you could hold but that number would be system dependant and you'd just have to experiment to find that number.
2
) That's a great idea to take those voltage signals and make them digital inputs. This way you'll also free up some more bandwidth giving you the option to increase the sample rate on your other channels. However, you won't be able to include any DIO channels in the same task with your other analog channels. You need to create a separate task for these digital input channels. Lines 0,1,2, and 4 will be reserved for communication with your SCXI chassis by the way. You also won't be able to do any buffered sampling like you can with the analog channels. The DIO for the PCI-6024E is only immediate and software-timed. (You must poll the status of the line with a software loop.)
Let me know if you have any other questions.

Digital waveform editor

If I use the Digital Waveform Editor to create a clock, can this clock signal be used as a my clock source? An example I am trying to reference for creation of my own VI is the Dynamic Generation and Acquisition - Demo.vi found in the Example Finder in LabVIEW 2012. In it the On Board Clock is used for both Generation and Acquisition. I would like to use a clock that I have already created in my waveform file because I know my other signal is working with it and the device under test when doing a signal generation and acquisition using a scope. Any advice on how to do this (if possible) would be appreciated.

tcarrico,
In terms of using the waveform file that you created directly as your clock source, this is not possible. However, if you wanted to output this waveform using a function generator and then use that signal as an external sample clock for your Digitizer, this would be more likely to work. Is this more along the lines of what you were thinking?

Digital waveform editor somewhere bundled in full, proffesional or suite?

Hi,
I recently discovered the digital waveform editor which seems quite usable for a project I'm working on. I downloaded the demo version, but I cannot save the files (it's a demo right). My question is whether this product is available in one of the bundles. At the university we do have access to allmost every LabVIEW product but I cannot seem to find this one. And before I go installing all DVD's I can find, perhaps there someone who knows whether and where I could find it.
Thanks in advance,
Mark

Digital waveform editorで作成した波形をPXIe-6536で出力

Digital waveform editorで作成した波形をPXIe-6536で出力したいのですが、どのようにすればよいでしょうか．
対応が正しいかわかりませんが、現状では以下のようなアプローチをとっております．
①Digital waveform editorで波形を作成
.hws形式のファイルとして出力して、
「NI-HWS Express(load)」に読み込み
デジタル波形グラフVIで出力を確認しました．
②PXIe-6536用にDAQアシスタントを作成
PXIe-6536でのデジタル出力
DAQアシスタント作成時画面でテスト波形の出力
NI CB-2162上で波形が出力されていることを確認
DAQアシスタント作成完了
というところまでを行いましたが、いくつか気になる点があります．
DAQアシスタント単体で実行すると、エラーが出る
「エラーコード-200077がDAQmx Write (Digital 1D Wfm NChan NSamp).vi:3で発生
Measurements: 要求された値は、このプロパティでサポートされている値ではありません。
プロパティ: Output.BufSize
要求された値: 0
最小値: 2
最大値: 4294967295」
DAQアシスタントとHWS読み込み用VIの接続を添付ファイルのようにForループ内に入れなければ接続できない
以後、サンプルレートの設定などを行うにはどのようにすればよいか．
といった状況です．
当方、Labviewに関しては全くの初心者であるため、上記のような方法が適切であるかわかりません．
至らない点も多いかとは思いますが、お気づきの点がございましたらご意見いただけますようお願いいたします．

Digital waveform editor & fichiers.hws

Bonjour,
J'utilise une carte PXI 6542 pour envoyer diverses sequences numériques à un système électronique, j'utilise le Digital WaveForm Editor qui est plutot pratique pour faire des modifications ponctuelles (à la sourie) sur des signaux (par exemple modifier le debut ou la fin). Je peux egalement créer des signaux directement avec labview, si ceux-ci sont repetitifs et pas trop complexes.
L'ideale, est de pouvoir utiliser les deux manières de dessiner les signaux numeriques. Mais je n'arrive pas à enregistrer à partir de labview un fichie.hws qui aurait des noms (voir même des couleurs) paramétrables.
Ma question : Comment enregistrer un fichier.hws avec des noms de signaux que l'on retrouverai lorsqu'on ouvre ce fichier.hws avec le Digital Waveform Editor ???
Merci.

Bonjour,
Pardonnez mon français, je n'ont pas parlé français depuis le lycée. Afin d'écrire un dossier et faire apparaître les noms de signal dans le DWE, vous devrez éditer le dossier utilisant une bibliothèque HDF5. On est disponible ici:
http://digital.ni.com/public.nsf/allkb/CB8A7F8090900F6C86256CC700033816
Les noms de signaux viennent du "name" corde dans le dossier HDF5. Si vous n'êtes pas très familiarisé avec HDF5, alors il peut être très difficile d'appeler les signaux. Vous pouvez également consulter le poteau suivant de forum de discussion:

Generate digital waveform form a read from spreadsheet.vi

Hi, I'm very new to LabView and am having some problems in completing what I believed would be a very simple task.
I am using the Read from Spreadsheet.vi to read in an Ascii tab delimited file that I created in Matlab (the file is simple a vector of 1's and 0's that represent a binary stream) All that I want to do is take the output from this and generate a digital waveform corresponding to the 1's and 0's in the array but I cannot find a way of doing this.....
Help much appreciated,
Thanks.

You should be able to just run your data straight in to the digital write function as long as you select the correct port width of your hardware.
If you want to do it with a digital waveform it's a bit trickier, the digital waveform data type is a surprisingly complex animal.
There might be a better way to do it, but this is what I've had to do in the past...
The "build digital data" function needs a 2D array in, so convert your 1D array into a 2D.
Then the digital data can be input into a Build Digital Waveform.
Then the digital waveform can be output with the write digital waveform.

Can Discoverer 9iDS be launched from Forms9i

I am wanting to launch Discoverer, run a report and save the results on the file system or in the database, from Forms 9i. Is there a RUN_PRODUCT type thing or is the only way of doing it HOSTing out and issuing Commands on the command line.
I don't want the forms user to have to do anything but press a button to kick off the process.

How can you add comments to a text file while using a Digital Waveform vi?

Hi. I'm very new to Labview. I have a txt file of 1's and 0's wired to a "read from text file" which is then wired to a "spreadsheet string to digital.vi" ("digital waveform") and lastly to a graph. I want to add notes to the txt file that will not be read in the digital waveform. i.e. Like how you use // or /* in a C++ program to show that you are writing a comment and not code.
Labview version: 8.5
Thank you

You will just need in your text file a line at a time. Search the string for the characters // or /*. If it finds them, then loop back and read another line. If it doesn't find them, you must have a good line of data and you can pass on to the next part of your cod.

How to control individual channel of signal generated from digital waveform generator?

Digital waveform generator has 8 channels. I need to generate two different signals to HSDIO. How to modify and control two different channels? Also, how to translate pin outs from PXI-6541 to channels? I need to control signal into pin 1,3,29,and 31 individually.
Thank you!!
Solved!
Go to Solution.

You must combine your individual data into an array. The digital waveform is simply a digital representation of the binary array. It still boils down to bit 0 of each array element going to channel 0 (or the first channel you specify in Create Dynamic Channels). The next bit goes to the next channel. My last post is quite clear. To display the array in binary, right click on an array element, then select Display Format, then select Binary. You can also right click on the element, select Visible, then select Show Radix to display the small b before the number. One more thing, in the Display Format window, uncheck the box next to Use minimum field width. Then set the numeric just under the box to 8. Then select Pad with zeros on left in the box below.
You should not use waveforms until you learn more about how the HSDIO operates on input data. It isn't hard to combine waveforms, but it also isn't as clear as using an array of U8 or U16 or U32.
Trying to explain further. The first number to be writen to the HSDIO will have this effect: Bit 0 (LSB) of the number gets written to the first HSDIO channel you specify. Bit 7 goes to the 8th channel you specify. If you don't specify 8 channels, the bits get ignored. So wiring in one number will produce only one bit on each channel. In other words, the number already combines the bits of all the channels you specify. You don't combine anything yourself. Look again at my picture on my last post. By wiring in an array, you cause a bit pattern to be generated.
I hope this is more clear.

How can I migrate Adobe digital edition and its library from an old computer to a new one?

How can I migrate Adobe digital edition and its library from an old computer to a new one?

Pertains to a Windows machine..
Definitely get other opinions on this. I last did this myself in 2010.
The most important thing, is to make sure you have an account (which I think you must have, or you probably couldn't have posted here).
As I recall, I downloaded ADE to my new computer, launched the software, authorized the new computer by supplying my login, and then just moved the 'My Digital Editions' folder to the new machine.
Be sure to de-authorize your old machine after you have done all of this, or over time you could end up exceeding your 'simultaneous devices'-limit for accessing your materials. I suspect that *from within the app itself, while it is still installed on your old machine* may be your only opportunity to do this. It is certainly the best/easiest.
Hey Internet! Have you done this more recently than I? If so, please chime in to make corrections or add detail.
